We
believe that a sofa is a solid object upon which one can settle down
just as one pleases and be active in contemplative stillness. But
we're making a big mistake there. De facto, it is an unimaginable
system that consists of 99.9999... percent nothing and an infinitesimal
trace of pollution – matter, which for its part is formed by
ghostly material waves that retreat from every attempt to access them.
To be precise, the part of a sofa mentioned is only a hard shadow
from the space above, a local irregularity of space-time geometry.
Still, you can sit on it.
